I just purchased a B1700 with 567 hours on it. The engine won't start and has low compression, 190-210 on all 3 cyl. I add a small amount of oil to the cyl. and the compression pegs my 300lb gauge. So I suspect bad rings. The previous owner said a rodent chewed through his air filter and he sucked in dirt for 9 mounths before he realized it. Anyway, I've got the pistons out of it and bought new rings from the dealer.The cylinders looked good after a quick hone job. I need to file the rings to size so I need the ring end gap specs. And the head bolt torque and rod bolt torque. I asked the dealer if he could help me, but he said he was too busy. I can't find any specific imfo online. Any help would be appreciated as I'm so excited to get this thing back together ASAP! ANYONE HAVE A SHOP MANUAL FOR A SIMILIAR ENGINE??? Thankyou!!!
